My computer screen isn’t wide enough to allow me to get the Galleon on the shelf. I’ve had this problem before where something was at the edge of the screen. If you’re having this problem, hold down CTRL and the minus sign (-) to zoom your browser page out. You should be able to get things now.

You can also click the letter Harry’s reading. On the table by the bed, you can also click the third card on the right and next to it, the letter with sneakoscope on it (looks like a small bottle to me, though).
